Vehicle Terminal Data Package Generation for Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of vehicle systems and data collection in data centers leads to elevated data transmission loads, making it difficult for data centers to manage collected vehicle data effectively, particularly in CAN communication where collision prevention requires adjusting and managing transmission timing.
Innovation Solution
A control method and terminal configuration that receive vehicle information messages, extract relevant data, generate data packages based on transmission cycles and frequencies, and transmit these packages to the data center, with user agreement and event messages, to optimize data collection and reduce transmission load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicle data is collected and transmitted to data center, then data collection capability is improved, but data transmission load increases
Solution Approach 1:
The patent segments vehicle data into different types (first type data requiring immediate transmission, second type data for periodic transmission, third type data for event-triggered transmission). This segmentation allows the system to collect comprehensive data while managing transmission load by sending different data types through optimized pathways, thus resolving the contradiction between improving data collection capability and reducing transmission load.
Solution Approach 2:
The patent implements periodic transmission for second type vehicle data, where the terminal periodically sends collected data to the data center based on predetermined time intervals. This periodic action reduces instantaneous transmission load while maintaining continuous data collection capability, effectively resolving the contradiction between these two objectives.
2Reliability
If transmission timing is adjusted to prevent collision in CAN communication, then communication reliability is improved, but transmission efficiency deteriorates
Solution Approach 1:
The patent segments data transmission into different priority levels and time slots. First type data is transmitted immediately when available, second type data is transmitted periodically during low-load periods, and third type data is transmitted upon specific events. This segmentation ensures reliable communication by preventing message collisions while maintaining reasonable transmission efficiency through optimized scheduling.
3Device complexity
If data center manages all collected vehicle data, then data management capability is improved, but system complexity increases
Solution Approach 1:
The patent extracts and processes data classification and filtering functions from the data center and relocates them to the vehicle terminal. The terminal autonomously classifies vehicle data into different types and filters out unnecessary data before transmission. This extraction of processing functions reduces the burden on the data center, simplifying the overall system while maintaining effective data management capability.
Data Source
AI summary
A control method for a terminal mounted in a vehicle includes: receiving at least one vehicle information message; extracting at least one piece of vehicle data from the at least one vehicle information message; generating a data package to be transmitted to a data center by grouping the at least one extracted piece of vehicle data into a designated unit; and transmitting the generated data package to the data center.
